SPECIFICATION formingl part of Letters Patent No. 771,450, dated October4, 1904.

Application filed May Z1, 1903y T all 7.1111077?, t 717/14/ conc/W71,.-

Be it known that I, GABRIEL ZAHHUANZ, a subject of the Emperor ofRussia, and a resident of Berlin, Germany, have invented certain new anduseful Improvements in Turbines, of which the following is aspecification. My invention relates to turbines intended to be driven bysteam, gases, vapors, or liquid under pressure. It refers most particuiolarly to turbines Vin which U-shaped guide and rotary channels form oneor more spiral coils of windings whose axes encircle the turbineaxis;and it consists of certain novel features hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, in which- Figure lis a sectional view of a steam-turbine with coils constructed accordingto my invention. Fig. 2 is a cross-sectional view of 2o Fig. 1 on theline 2 2. Fig. 3 is a front view, partly in section, of the rotarymember of a coil-ring'. Fig. 4 is a side view, partly in section, ofFig. 3. Fig. 5 is a front view, partly in section, of the guide memberof a coil-ring.

Fig. 6 is a side view, partly in section, of

Fig. 5. l

The turbine, as shown by Figs. 1 and 2, has three coils consisting eachof four systems of windings. I construct each coil in form of a 3o pairof rings, so that a rotary ring a and a guide-ring b constitute togetheran independently-working coil-ring. The two members of each coil-ring(separately represented by Figs. 3, 4 and 5, 6) are respectively fittedinto recesses provided in the opposing' faces of a rotary frame e and toa guide-framef, the parts being secured in any convenient way-- as, forinstance, by means of keys ckagainst circular displacement and by meansof lateral rings CZ against axial displacement.

struction of coils allows of various practical applications. By fitting'different numbers of coils of the same, as well as of differentpatterns, I am enabled to form steam-turbines of differentoutputs.Byreplacingoneofthecoils in the turbine-rim with a pair of simple ironrings Without any channels I am enabled to This con- Serial No. 158,067.(No model() form a turbine capable of increasing its output on replacingthese simple rings with rings forming a coil. On the other hand, by re-5o versing one or more of the coils I am enabled to form a turbine withreversible motion. My invention has besides said features the advantageof extremely facilitating the manufacture and the duplication of parts,as well as 5 5 the repairs and alterations.

The invention may be variously modified. Thus the rotary members ofseveral coils may be united into one ring. In the same way the guidemembers of the same coils may be united 6o into one ring. Further, thetwo rings of a coil instead of being situated one over the other mayreceive the U-shaped channels laterally, so as to be `fitted to a guideand a rotary frame side by side. Further, the rings 6 5 may have anyother cross-section instead of being rectangular, as represented.

lVhat I claim as new, and desire to secure by Letters Patent, is-

1. A turbine comprising two members one 7o rotatable relatively to theother, and a plurality of independently-removable rings secured to theopposing faces of each of said members and provided with channelsarranged to form a spiral path for the drivingI medium.

2. A turbine comprising two members one rotatable relatively to theother, and coperating rings secured to the opposing faces of each ofsaid members and provided with channels arranged to form a spiral pathfor the 8o driving' medium.

3. A turbine comprising two members one rotatable relatively to theother, and a plurality of independently-removable rings secured to theopposing' faces of said members 85 in pairs, the rings of the same pairhaving channels adapted to register and to form a spiral path for thedriving medium, the path of one set or pair of rings having a directionor pitch opposite to that of another set or 9o pair, so that the turbinemay be reversed by substituting one set of rings for another.

4. A turbine comprising two members one rotatable relatively to theother, and a plurality of cooperating rings arranged in pairs to thisspecioation in the presence of two subon the opposingsurfzioes of thesaid members soriblng witnesses. and provlded with channels adapted toregister lmd to forrn a spiral path for the driving GABRIEL AHlKJAN/J'medium, said path being continuous within Witnesses:

the two rings of one pair. WOLDEMAR HAUPT,
